Answer:<em> </em><em>Second Option </em>

18

Step-by-step explanation:

\frac{3}{4} of a number is:

\frac{3}{4}x

\frac{3}{4} of a number is increased by \frac{1}{2} is equal to 14

This is:

\frac{3}{4}x+\frac{1}{2}=14

Now we solve the equation for the variable x

\frac{3}{4}x=14-\frac{1}{2} →  Subtract \frac{1}{2} on both sides of the equation

\frac{3}{4}x=\frac{27}{2}

x=\frac{27}{2}*\frac{4}{3} →   Multiply by \frac{4}{3} on both sides of the equation

x=9*2

x=18

Which number line represent the solution set for the inequality 3(8-4x)&lt;6(x-5)
quester [9]
Eliminating parentheses, you have
  24 -12x < 6x -30
Adding 30 +12x, you have
  54 < 18x
Dividing by 18 gives
  3 < x

The appropriate number line is the one that shows the solution set as all values of x that are greater than 3.
